area online calculator that can calculate the area of a square from the length of a side.
The calculator has several features allowing it to make surface calculations. It is thus possible to calculate the surface of a square, also known area of a square with the area_square function, but also the surface of a rectangle , or the surface of a circle .
The area of a square is the area bounded by the square. The area of a square is given by the formula `l^2` where l is the length of a side.
Thus, calculating the area of a square whose side length is 3 is done by typing the following formula area_square(`3`) , after calculation, the result 9 is returned.
It is also possible to do symbolic calculation and calculate the area of a square whose side length is 1+x, by typing the following formula area_square(`1+x`) , after calculation, the result is returned.
To apply the different calculation formulas, several quizzes on the calculation of the area of the square, the rectangle, and the circle are proposed.
area_square(`3`) returns 9
